The ARC is not cleared to ensure that all data is cached. 26# 27# This is basically a copy of the sequential_reads_cached test case, but with 28# a smaller dateset so that we can fit everything into the decompressed, linear 29# space in the dbuf cache. 30# 31 32. $STF_SUITE/include/libtest.shlib 33. $STF_SUITE/tests/perf/perf.shlib 34 35function cleanup 36{ 37 log_must zfs destroy $TESTFS 38} 39 40log_assert "Measure IO stats during sequential read load" 41log_onexit cleanup 42 43export TESTFS=$PERFPOOL/testfs 44recreate_perfpool 45log_must zfs create $PERF_FS_OPTS $TESTFS 46 47# Ensure the working set can be cached in the dbuf cache. 48export TOTAL_SIZE=$(($(get_max_dbuf_cache_size) * 3 / 4)) 49 50# Variables for use by fio. 51if [[ -n $PERF_REGRESSION_WEEKLY ]]; then 52 export PERF_RUNTIME=${PERF_RUNTIME:-$PERF_RUNTIME_WEEKLY} 53 export PERF_RUNTYPE=${PERF_RUNTYPE:-'weekly'} 54 export PERF_NTHREADS=${PERF_NTHREADS:-'16 64'} 55 export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'1'} 56 export PERF_IOSIZES=${PERF_IOSIZES:-'64k'} 57elif [[ -n $PERF_REGRESSION_NIGHTLY ]]; then 58 export PERF_RUNTIME=${PERF_RUNTIME:-$PERF_RUNTIME_NIGHTLY} 59 export PERF_RUNTYPE=${PERF_RUNTYPE:-'nightly'} 60 export PERF_NTHREADS=${PERF_NTHREADS:-'64'} 61 export PERF_SYNC_TYPES=${PERF_SYNC_TYPES:-'1'} 62 export PERF_IOSIZES=${PERF_IOSIZES:-'64k'} 63fi 64 65# Layout the files to be used by the read tests.
